Résumé
Effective flood early warning information dissemination is critical for both real-time operational flood management and long-term planning. Although not all floods have the same magnitude, communities should be informed well on time about their likely occurrences so that they get prepared and respond appropriately. This requires dissemination of reliable, timely and effective warning messages to relevant institutions and subsequently to people residing in flood prone areas. This study looks at current Namibia flood early warning coordination of episodic floods in Cuvelai-Etosha Basin. Primary data were collected through face-to-face interviews with representatives of relevant institutions and affected communities residing in flood prone areas. Documenting the experiences of the source and intermediate institutions, civil protection unit responsible for managing disasters, local authorities, nongovernmental organisations and local communities on the study area provides an important insight about the current warning coordination and proposed improvements for future flood warning coordination in the basin. The current early warning communication is a one-way process, with those issuing warnings not fully aware about the capacity of the recipient institutions and individuals to translate the warning messages into meaningful context to trigger desired response. Warning information is poorly understood by communities living in flood prone areas. Despite the absence of official warning set-up, 78% of respondents living in flood prone areas received flood warning information based on the current flood warning arrangement. However, of the above percentage, 62% of respondents did not understand the warning information. The absence of national policy on disaster management hamper the implementation of effective flood early warning coordination at both national and local level. As a recommendation, Namibia need to develop and adopt a national disaster risk management policy to act as a regulatory tool for disaster management and control. There is also a need to promote and strengthen local community means of communication and capacity to play a key role in information sharing and dissemination to enhance effective response
